EN2R-9025 0502R8-NE
CONSTRUCTION AND WORKING PRINCIPLES oprerated by the 2nd coil (M). This 2nd coil also operates the integrated modulation function by loading an integrated regulator diaphragm (N) with the required force through applying the appropiate current (based on % PWM input) which is determined in the electronic circuit that is connected to the gas control. When the 2nd coil is energized at heat demand, but a 0% PWM input, the plunger is moved down and the servo valve opens. At this moment “working gas” can flow to the supply orifice (O). At the same moment the minimum rate gas can flow through the servo valve (K) and the minimum rate adjustment screw (D) directly to the outlet. When now the PWM input (heat demand) rises, the current rises, the load on the regulator (N) rises and the pressure of “working gas” in the servo system is being built up. At a certain point this pressure opens the main valve (B) and the outlet pressure rises. Now the main valve is modulating and the outlet pressure is controlled by the balance between generated forceon the plunger and outlet pressure through the regulator diaphragm. The higher the force becomes, the higher the outlet pressure will be and vice versa. The outlet pressure can be limited to a maximum value by setting of the maximum servo pressure regulator (C). This maximum regulator is parallel to the integrated modulating regulator. This means that the lowest of both settings will determine the actual outlet pressure. When the 2nd coil (M) is de-energized, the servo valve closes and the supply of minimum rate gas and “working gas” are shutt off. The load of the regulator diaphragm is released, the “working gas” can bleed to the outlet through the regulator seat and the main valve closes.
The VK4105G gas control contains a first direct electric ON/ OFF safety valve (A) and a second ON/OFF and modulating servo operated main valve (B). The modulating valve maximum output pressure can be limited by a maximum pressure regulator (C). The minimum output can be adjusted by a throttle adjusment screw (D). Description of the direct electric operator The direct electric operator (RAC) is built up with a valve seat that is machined in the die cast body (E), the coil plate assy that forms the upper part of the product (F) and the plunger assy as moving part (G). A sleeve (H) guides the plunger assy (G) and is assembled between body and coil plate assy. If the solenoid is energized the plunger is pulled-in and moves upwards. So the safety valve, which is directly attached to this plunger, is opened. The impact of the plunger on the stop is damped by a rubber silencer in the plunger. Description of the servo operated modulating main valve The main valve (B) is a spring closed and diaphragm (J) actuated valve located in the main gas passageway between the direct operated safety valve and the outlet of the gas control . The main valve is opened by the servo systems “working gas” acting against the main valve diaphragm (J). So the position of the main valve (B) is controlled by the “working gas” pressure in the servo system. The “working gas” is obtained from the main gas stream through the servo valve (K) and a supply orifice. The servo valve is located parallel to the main valve and is
